Advanced “bèi” Sentences
被字句（高级）
How it works
At HSK6 level, 被字句 (bèi zì jù) is not only used for simple passive meaning. Advanced passive structures often highlight:
the effect on the subject
an unwanted or unexpected result
the subject’s lack of control
written or formal passive description
It can also appear with omitted agents when the performer is unknown, unnecessary, or intentionally left vague.
The pattern
Example sentences
很多真正重要的问题，往往不是被解决掉的，而是被长期掩盖之后才突然集中爆发出来的。
Many truly important problems are often not solved, but rather suddenly erupt only after being covered up for a long time.
这份报告原本只是内部参考材料，后来却不知怎么被传到了外面。
This report was originally only for internal reference, but later somehow got circulated outside.
一个人如果长期被误解，却又无法及时解释清楚，那种压抑是很难真正排解的。
If a person is misunderstood for a long time and is also unable to explain things clearly in time, that kind of repression is very hard to truly relieve.
Key point
Advanced passive sentences often shift attention from the doer to the affected subject and the resulting state.
